My understanding from talking to cyphermox is that we have all of the GRUB modules in order.

I am not sure, if this is true. As far as I understand it, the Grub modules are under /boot/grub, which is in the encrypted LUKS container. The Grub bootloader is on the EFI-System-Partition and should unlock the LUKS container to load the kernel, but cannot do it, because it does not have all the necessary modules.
